10mm-12mm thickness S550QL steel welded property

A709GR50 steel plates are used in construction steel structure, construction machinery and other steel structures, such as construction steel structure, construction machinery, mining and mountain machinery, heavy trucks, bridges, pressure vessels, etc., especially for requirements with better weldability And tough construction and construction machinery parts. The product S550QL steel has been exported to South Korea, Taiwan and other places, and the cumulative export volume has reached more than 10,000 tons.

The company now has S550QL steel oversea market department, sales and supply department, finance department, logistics department, technical equipment department, quality management department, production department and other departments. The staff with college degree or above accounted for more than 80%, and there were more than S550QL steel 30 professional and technical personnel. The LSAW pipe production line can produce welded pipes with Φ350-1800mm, wall thickness 6-80mm, and length 2-12m.

Now many manufacturers will use CNC equipment to complete the steel plate cutting processing, this processing method is also gradually increasing, but if you want to make the processing effect meet the specifications and standards, the control requirements of operation technology are also relatively high. Now there are many kinds of steel plate cutting, during the actual processing, it is necessary to select the appropriate processing method according to the cutting requirements of steel plate, so as to achieve the ideal processing effect for S550QL steel.

Vanadium is a weak deoxidizer. Adding vanadium into S550QL steel steel can reduce the adverse effects of carbon and nitrogen, effectively improve the strength, but sometimes also increase the tendency of welding hardening, vanadium is also a commonly used trace alloy element.

The company strengthens process management and pays attention to assessment. One of the key points of good service is to strengthen the process management and improve the evaluation mechanism. Make the after-sales service system more perfect and provide better service for customers.
